The SENTINEL-1 Toolbox (S1TBX) consists of a collection of processing tools, data product readers and writers and a display and analysis application to support the large archive of data from ESA SAR missions including SENTINEL-1, ERS-1 & 2 and ENVISAT, as well as third party SAR data from ALOS PALSAR, TerraSAR-X, COSMO-SkyMed and RADARSAT-2. The various processing tools could be run independently from the command-line and also integrated within the graphical user interface. The Toolbox includes tools for calibration, speckle filtering, coregistration, orthorectification, mosaicking, data conversion, polarimetry and interferometry.

The SENTINEL-1 Toolbox is being developed for ESA by Array in partnership with DLR, Brockmann Consult and OceanDataLab.

Open Source Development

The Sentinel Toolboxes and full source code is distributed freely under the GNU GPL license.

Open source makes software inherently independent of specific vendors, programmers and suppliers. The software can be freely distributed and shared by large communities including the source code and the right to modify it. This ensures that there isn't a single entity on which the future of the software depends on and allows for unlimited improvements and tuning of the quality and functionality of the software.

As open source, future evolution and growth of the toolboxes will be possible by the community of users and developers that contribute back to the project.
